Title: Trimming of film capacitor
Inventor: ARAKAWA MASAYUKI
IPC: H01G4/06
Filed: 1987-07-31
Abstract: PURPOSE:To easily execute a fine adjustment without adversely affecting a characteristic and the reliability of a film capacitor by a method wherein a slit is formed by a trimming operation in a lower-layer electrode layer of the film capacitor, a slit part is formed by extending said lower-layer electrode layer to the outside of a dielectric layer and a capacitance value is adjusted by cutting the slit part. CONSTITUTION:An Ag/Pd-based lower-layer electrode layer 12 is printed on an insulating substrate 11 such as an alumina substrate or the like by a screen printing process; the printed layer is dried at 150 deg.C. After that, the lower-layer electrode layer 12 is irradiated with a YAG laser beam; it is trimmed; a slit 13 is formed. Then, a dielectric layer 15 is printed in such a way that a whole part excluding an extraction electrode part 16 of the lower-layer electrode layer 12 and one part of a slit part 17 is covered; the printed layer is dried. An upper-layer electrode layer 18 is printed and dried; after that, the lower-layer electrode layer 12, the dielectric layer 15 and the upper-layer electrode layer 18 are baked simultaneously at 850 deg.C in the air. A one-dot chain line part of the slit part 17 is irradiated with the YAG laser beam; the slit part 17 is cut. During this process, the lower-layer electrode layer 12 and the surface of the insulating substrate 11 are cut slightly; other layers in a periphery are not affected.

Title: Method for electron beam exposure
Inventor: OSADA TOSHIHIKO
IPC: H01J37/302
Filed: 1981-11-26
Abstract: PURPOSE:To reduce the overhead of the titled electron beam exposure by a method wherein, when performing the electron beam exposing method of vector scanning system, said exposing method is conducted by making a deflection correction  even when the stage is in moving state when the position whereon an electron beam is  to be irradiated is within the scannable range. CONSTITUTION:When the exposing process for a pattern is finished and the movement  of a stage 3 is started (F), this movement is performed by having a stage control circuit 6 function to operate a motor 4 in accordance with the command given by CPU 7.  A laser counter 5 detects the position of the stage 3 at all times, and transmits the same to a deflection correcting unit 9. The next pattern data is outputted from a pulse  generator PG8 by the command outputted from CPU 7 simultaneously with the start of  movement, the unit 9 makes correction of the signal indicating the position of the stage 3 on the above pattern data and transmits to a D/A converter 10. An analogue signal  is outputted to a deflector 12 as the deflection current wherein a deflection correction  has been made through the intermediary of an amplifier. At the same time, an electron beam 2 is radiated in accordance with the command of the CPU and deflected to the prescribed position by the deflector 12. Accordingly, the exposure is started from  the point F.
